Melting Point and Boiling Point of Organic Compounds Bongo‚ Sayre‚ J1 1Student‚ Organic Chemistry 1 Laboratory / B11‚ School of Chemical Engineering‚ Chemistry and Biotechnology‚ Mapúa Institute of Technology ABSTRACT The melting point of a substance is the temperature at which the material changes from a solid to a liquid state while the boiling point is the temperature at which it changes from liquid to solid. In this experiment‚ the main objectives were to determine the effects of the following

------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The temperature at which a compound turns from a solid state to a liquid state is known to be the melting point. On

Sample Lab Report for CHM 152 Name Lab Partner(s) Abstract: The physical properties‚ including the boiling point‚ density‚ and refractive index were measured for unknown liquid #16. The infrared (IR) spectrum of the compound was also taken. Based on the data collected‚ it was determined that the compound was likely to be salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical

BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand

1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting point. Boiling

Boiling Point Lab Introduction: The purpose of this lab is to learn about the calibration of a thermometer. In addition‚ we also investigated the boiling point of an unknown liquid to determine its identity. Chemical Responsibility: 1. Make sure to use glycerine (lubricant) and a towel to safely insert the thermometer into the rubber stopper. 2. Carefully operate the Bunsen burner and make sure to use rubber gloves when handling the boiling water of beaker 3. Always wear goggles
